I'm not arguing that gay men should be sluts. I'm just saying I've met some shallow gay guys who act like anyone over 30 is too old or like they're just too good for half the men out there and this is sort of a reaction to that.
Some people just have... interesting standards!
Like the girl I approached in a club. After some conversation she told me that she's only interested in guys older than her and taller than her. I was drunk and decided we should measure who was tallest right then. I told her to take her shoes off since she had high heels, and then we were standing back to back next to the dance floor and getting one of her friends to measure who was tallest.
I was taller so I guess she was interested.
She was a lousy lay though. Not that I was any better that time. But that's a very different story... 
I used my example because I know my situation best. From what I gather, many guys feel the same way. They're not socially stunted or anything, it's just that there aren't opportunities. And it gets worse the older you are. When you're around 18-20, it's easy to run into fine girls which are single. When you're 25, not so much so. So, if you miss the proper "launch window" because you had better things to do than getting stuck in a binding relationship, it becomes difficult later to change that.
In that case, I think dating services are in fact a pretty good option, because as you said, at least there you know where you stand and you can dispense with all that crap about not knowing what the other one expects. Might try that myself one day.
Unless Czechia is completely different from Germany and half the rest of Europe, your ideas about such a launch window sounds very inaccurate.
From 25 and up it gets more difficult to be single and remain friends with couples, that is true. But there's not really a lack of singles in their late twenties. And even if there was, there no reason not to go a couple of years up (for women) or down (for men) from your own. The opposite direction is also possible, though rarer.
From what little I can glean though, it seems you simply have problems escalating an established or budding friendship into a sexual relationship? If I can ask: Do you find yourself too quickly in the "friend zone", or are you actively being refused when you try to escalate things? How is your luck with simply asking a girl to go and hang out and do something?
Probably because you are going about it with the intention of scoring. Every non-ugly girl you talk to, your brain is like we can potentially have sex with it and it puts you in the mindset of a hunter. The trick is in telling your brain to buzz off and just be normal.
Being on the hunt doesn't matter. As I've said before, even when I'm in a relationship the first three thoughts going through my head when meeting a girl is:
1. Would I have sex with her?
2. Would I want to be in a relationship with her?
3. She's talking, let's try and pay some attention...
Well, something like those three at least. Those were my thoughts when I couldn't get a girlfriend, those are my thoughts when I'm single, those are my thoughts when I have several potential girlfriends, and those are my thoughts when I have an exclusive girlfriend. Not that I would admit it in RL, and not that I would act on anything in that last example. Thoughts never changed, but results changed as I gained knowledge and experience.
Whatever your intentions, if you come out as needy, clingy or creepy, you won't get anywhere.
But all correct behaviours can be learned.
Meh, if you don't think you'll get in a relationship, chances are, you won't. And visa versa. If you do, you will.
That's either inaccurate or a tautology.
I'm too ugly, too short, and too fat. Plus, I have bizarre fetishes, and I'm obsessed with a race of people who don't even exist, while at the same time having a foaming-at-the-mouth hatred of my own species. And of course, extreme shyness.
